Who runs this, and by what rules
OVERROUND is built and run by one person: Josh, a data engineer who posts as @JBowzDataGuy, operating as JBowz Holdings LLC. The pipeline ingests public on-chain Polymarket activity, grades every resolved position against the price actually paid, and publishes the results: a skill-ranked leaderboard, a graded ledger of every alert ever sent, and a free wallet checker.
Why trust a site run by one person
You should not have to. The site is built so its claims can be checked without trusting its author: every number traces to resolved on-chain events anyone can verify, the methodology is published in full with its limitations, the alert record grades itself in public with losses included, and the validation report was committed to publication before its results existed. The receipts ledger publishes its own arithmetic identity, so silent edits would be detectable by any reader.
Corrections
Errors are corrected the same way alerts are graded: in public. When a published number or graded row is found to be wrong, the correction is applied and noted on the affected page rather than silently swapped, and anything material enough to change a conclusion is called out where the conclusion was drawn. Grading itself is mechanical: alert rows are recorded at detection, frozen, and settled by each market’s recorded resolution, with no editing after the fact. Voided markets are excluded from the record and labeled as such.
Methodology changes
The scoring method is versioned and dated on the methodology page. When the method changes in a way that moves rankings, the change is recorded there with its date and reasoning; historical grades on the receipts ledger are never rescored retroactively.
